A particle accelerating tube includes an insulating cylinder defining a first air-tight chamber and having evacuation means connected thereto and containing an assembly of accelerating electrodes aligned along an axis parallel to that of the cylinder, together with a source of particles to be accelerated disposed outside the air-tight chamber but inside the insulating cylinder, and a target mounted in a second air-tight chamber, an aperture for the passage of the charged particles providing communication between the two air-tight chambers. The accelerator tube (Fig. 2, not shown) of a neutron generator, Fig. 1, is formed by a laminated or moulded cylindrical stack of apertured aluminium discs (31) clamped between annular insulators (37) which house sections of a potentiometer (38) from which the voltage for the discs is tapped. The complete stack is mounted in an evacuated chamber 20, Fig. 1, formed by insulating cylinder 21 and metal end plates 24 and 25, which support a target 27 in a holder 28, and a deuteron source 4 and insulated terminal 30 for the focusing electrode 29, respectively, the whole being evacuated by pumping system 7a, 7b, 7c, 7d.

Filed: 1970-07-28
Abstract: 1307636 Fluid heating store RAYPAK Inc 28 July 1970 [6 Nov 1969] 36442/70 Heading F4W  A fluid heating appliance for outdoor use comprises a combustion chamber 10 with a burner 16 below it spaced from an outer jacket 34 and a top 4. A sleeve 66 surmounts a tank of horizontal water tubes 31 at the top of the combustion chamber. A collar 72, which may comprise spaced plates or insulation is spaced from the top 4 to leave exhaust gas outlets 78. The top of the outer casing 34 is bent inwardly at 70 to leave a space 5 between the collar 72 and the main part of the casing. Forward opening 42, 58 are arranged at two levels in the sides of the casing 34. A baffle 76 extends from the sleeve 66 to terminate just above the inwardly bent part 70 of the casing 34. The burner is enclosed by a skirt spaced from the outer jacket 34. In operation, air enters through the louvred opening 42, 58 and top inlet 5, and air for combustion reaches the burner through ouvred openings in the skirt. The remaining air flows upwardly in the space between the jacket and combustion chamber and between the spaced plates of the collar 72 to mingle with the exhaust gases flowing over the top of the sleeve 66 at 68 to exit from the gap 78 surrounding the top 4. In conditions of moderate or high wind Fig. 5 the arrangement of the inlet 5 and the spaced louvred openings 58, 42 prevents excessive draught, and the effect of the flow through the opening 5 over the baffle 76 and between the plates of the collar 72 induces a satisfactory exhaust gas flow. A divider in the space above the sleeve 66, a rim at the bottom of the top 4 and baffles in the exhaust gas outlet 78 prevent driving rain from reaching the combustion chamber. In a modification, the inwardly sloping upper part of the outer casing has a vertical extension spaced from the collars 72, and there is no baffle extending from the sleeve 66. The collar may be supported in hollow brackets through which cooling air flows to a central stack in the cover, the exhaust gases flowing on either side of the brackets to the outlet.

Title: Thermal process of preparing magnesium
IPC: C22B5/06
Filed: 1961-10-12
Abstract: <PICT:0997402/C6-C7/1> In a process for the production of magnesium by reduction of dolomite with ferrosilicon or other metallic reducing agent, the reaction mixture passes downwardly through a reaction chamber while a current of inert scavenging gas (e.g. hydrogen or rare gas) is passed countercurrently through it.  Simultaneously the colder parts of the apparatus may be scavenged with currents of the same or a different inert gas to prevent premature condensation.  A particular form of apparatus described consists of a reaction chamber 1 in which charge material 14 is supported by grate 2, spent material being discharged through valve 4. Fresh charge is supplied by feeding device 11 and is heated by electric elements 9.  The main stream of scavenging gas enters by pipe 5, passes upwards through the charge and carries magnesium vapour through conduit 7 to purification device 28, and thence condenser 15. Further inert gas is passed in through pipes 12. The condenser has two tubes 19, each being surrounded by superimposed casings 16, 17 and 18, and having within it a coolant pipe 20 fitted with baffles 23.  Tubes 19 are connected to the necessary vacuum pumps by pipe 25.  Vapour not condensing in chamber 15 is condensed in the condenser tube 19 in use until the latter is blocked.  It is then sealed off, and the solid magnesium melted out by heaters 24. The pressure in chamber 15 is maintained at 25-90 mm. of mercury.

Abstract: 1,017,636. Temperature control arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 24, 1963 [Sept. 27, 1962], No. 37537/63. Heading H2H. To prevent the liquid in a container 1 from exceeding a given temperature when an electrical heater 2 is energized, the latter is connected in series with a positive temperature coefficient resistor 3 thermally-coupled to the liquid and having a voltage-current characteristic with positively and negatively sloped portions. Fig. 2 shows two such characteristics T 1 , T 2  together with a load line R representing the heater 2, the characteristics corresponding to certain temperatures of the liquid and T 1  being so chosen that when heater 2 is initially energized an operating point P 1  is achieved whereby the resistor 3 has a low value and a large current flows through the heater 2. Resistor 3 is exposed to the vapour from the liquid so that as the liquid temperature rises the resistor characteristic moves towards T 2 , arrival at which brings the operating point P 1  to the negative (unstable) portion of the characteristic corresponding to rapid increase in resistor value. The operating point thus moves rapidly to P 2  to reduce the current through the heater 2 until the supply 4 is removed. The resistor 3 may be disposed so that its dissipated heat assists in heating the liquid, and thermal coupling between the resistor and liquid may be made through a bimetal strip which moves to contact the resistor when the given temperature has been reached. Application of the invention to heating solids is envisaged.
